The solution for sporadic charging is to have a pressure detector to determine a full tank, then an auto valve to open to charge, then detecting the pressure empty tank level to close the valve.
What is needed is the Banki nozzle size and the water usage at good water flow -- and the low water available to see what type of nozzle maybe needed to run the Banki under these conditions-- for possible full time usage and not sporadic use.

The key thing is to have two distinct states - no flow and full flow. If this could be done with a periodically fired flapper valve then that would work, but maybe there is some way to make a syphon system work where there is no valve.
